Fig. 1From: Near-infrared light reduces β-amyloid-stimulated microglial toxicity and enhances survival of neurons: mechanisms of light therapy for Alzheimer’s diseaseMicroglia cell viability and secretion of TNF-α and IL1-β (pg/ml) by microglia depending on the incubation time with Aβ (1 μM). A Cell viability determined using trypan blue solution. B TNF-α and IL1-β assayed by mouse-specific ELISA kits for measuring optical absorption. The cells were irradiated with low-intensity light at 808 nm with a light dose of 10 J/cm2. The data are presented as the mean ± SD (n = 8 replicates in each group); p < 0.05 indicates the data with a statistically significant difference (two-way ANOVA test)Back to article page
